PATCH 1/1 ARM: add Versatile Express defconfig
Being able to compile a major reference platform is helpful for me when developing on other archs using the same e.g. PrimeCells. I bet this is useful to others as well.

PATCH 1/1 ARM: add Versatile Express defconfig
Hi Linus,

Being able to compile a major reference platform is helpful for me when developing on other archs using the same e.g. PrimeCells. I bet this is useful to others as well.
Ignoring the politics surrounding defconfigs, I have a comment inline...

This will probably cause a compile-time error with a mainline kernel because the necessary hotplug functions aren't implemented for vexpress.

Beats me, it was part of the defconfig Colin recommended, Colin?

Does compile for me on 2.6.38-rc1 (after I avoid an compiler ICE on the NOR flash driver by deselecting it, I don't blame the kernel for that one tho):

Might this have something to do with it:

ARM: CPU hotplug: add Versatile Express hotplug CPU support
I don't know if it boots tho, if you pack up a Vexpress and mail it to my place I promise I will make more than just compiletests ;-)

Is the ICE similar to this? :
drivers/mtd/maps/integrator-flash.c: In function 'armflash_probe':drivers/mtd/maps/integrator-flash.c:262: internal compiler error: in remove_insn, at emit-rtl.c:3803 Please submit a full bug report,
with preprocessed source if appropriate.
If so, I reported that to the compiler guys in ARM and I think it got fixed in the 2010q3 codesourcery toolchain (not sure where it is upstream).

Great, I missed that! Feel free to hotplug away in your defconfig.

I'd swap one for one of your boards with the funky PMU, but I think some people might not be too happy about that.
